Benzyldimethylstearylammonium Chloride CAS 122-19-0

What is Benzyldimethylstearylammonium Chloride CAS 122-19-0?

Octadecyldimethylbenzyl ammonium chloride is a pale yellow liquid, a quaternary ammonium salt composed of a long-chain octadecyl group (C₁₈H₃₇), two methyl groups (CH₃), a benzyl group (C₆H₅CH₂) and chloride ions (Cl⁻).

Specification

Application

1.Textile industry
Softener: adsorbs on the fiber surface to form a directional arrangement, reducing friction between fibers (especially improving the stiffness of polyester and acrylic fibers).
Antistatic agent: neutralizes the surface charge of the fiber to prevent static adsorption during spinning/weaving (better when combined with glycerides).
Technical points:
The dosage is usually 0.5%-2% of the fabric weight, and the applicable pH range is (4-9).
It may affect the color fastness and needs to be used in post-dyeing treatment;

2.Oilfield chemicals
Application scenarios:
Drilling fluid sterilization: inhibits the reproduction of anaerobic bacteria and prevents the generation of H₂S gas (combined with glutaraldehyde to enhance the effect).
Corrosion inhibitor: forms a hydrophobic film on the metal surface to block water/oxygen contact (the corrosion inhibition efficiency for carbon steel can reach more than 70%).
Precautions:
It needs to be compounded with corrosion inhibitors (such as imidazolines) to cope with high temperature and high salt environments.

3.Other special applications
Papermaking industry: as a wet strength agent to improve the softness of paper (used in conjunction with polyamide epoxy resin).
Coating antiseptic: prevent water-based coatings from mildewing (addition amount 0.05-0.1%).
Agriculture: disinfection of greenhouse tools, seed coating and sterilization.

Features

1.Good surface activity: As a cationic surfactant, it can reduce the surface tension of the solution, help the liquid spread and penetrate, and enhance the detergent’s ability to remove dirt. ​

2.Strong stability: The chemical properties are stable. Under common temperature, humidity, and pH values, it is not easily decomposed by light, heat, and air, and is easy to store and transport. ​

3.Widely used: With its bactericidal and surface active properties, it is commonly used in many fields such as disinfection, cleaning, fabric softening, and petroleum corrosion inhibition.
